SHEET METAL ADAPTER "Fiied June 13, 1929 INVENTORS HAROLD E. BAl/N/VEA A/Vfl BY ROBERTF/il/NGE w A'rTQRNEY Patented May 20, 1930 UNITED STATES PATENT OFFICE HAROLD E. BRUNNER, OI LAROHMONT, AND ROBERT F. RUNIGE, OF IOI'tIlllS'J! HILLS GARDENS, NEW YORK, ASSIGNORS TO THE SKAYEI' BALL BEARING COMPANY, OF EABTFOBD,.OONNECTIGUT, A CORPORATION OF CONNECTICUT SHEET-METAL ADAPTER Application filed June 13, 1929. Serial No. 870,558.

The object of this invention'is to furnish a secure and economical device for mounting bearings on shafts and other journals, and one which is particularl useful in mounting hearings on lon s afts such as line shafts, upon which e bearing has to be moved for some considerable distance upon the shaft to bring it to its proper position. This invention also permits the bearing mounting device and the bearing to be placed in a. hanger box and handled as a unit and angle than is now mounted on the-shaft as a unit if desired.

The invention also relates to means for readily seating a-bearing on an adapter sleeve and for locking the parts in the seated position.

Another object of the invention is to afford an adapter sleeve and locking device made up of sheet metal parts.

And a still further object of the invention is to furnish an ada ter sleeve much thinner than has heretofore n employed in standard practice and also a sleeve of less taper employed. in standard practice.

According to standard practice the bore of the inner ring of the bearing is tapered at an angle of about two degrees, twenty-four minutes, and the adapter sleeve is made of solid metal and has considerable thickness because of the fact that the screw threads for the locking nut must be cut into an extension from the thin end of the sleeve. In order not to'unduly weaken the inner ring of the bearing in thus tapering its .inner surface, and to accommodate the thick adapter sleeve,

' it has been the practice in line shaft hangers to use a bearing frequently considerably larger than is necessary to support the load.

For our improved device a smaller sized hearing may be used than in prevailing practice, and the bearing is securely and permanently locked in position. The saving to the ultimate user of the bearings is quite great especially number of bearings, say for instance line shaft hangers in a factory. The bearing itself will be cheaper and we believe that our improved type of adapter can be furnished in installations requiring a large shaft hanger box and an elevation of a broken away section of a portion of line shafting. earing in longitudinal section is illustratedas being located in the box and mount ed on the shaft by means of a form of our invention, which is also shown in longitudinal section.

Fig. 2-is an under side view of the parts illustrated in Figure 1, and

Fig. 3 is an end view from the right-hand side.

In the illustrative embodiment of our invention shown in the drawings a section of line shaft 5 is shown mounted in a hanger box, the removable ca 6 of whichis shown. Mounted within this hanger box issa hear ing having an outer ring 7 adapted to have looking at Fig. 2

box and-an inner ring 8 which is intended to be rmly mounted upon. the shaft 5. These rings are shown held together by means of suitable rolling elements 9. The bore of the inner ring 8 is showntapering.

The parts above described are selected as standard parts with which our intention is adapted for use.

Our improved mounting comprises two 7 parts made of sheet metal. One of these parts 'isa sleve adapted to fit upon the shaft and to slide thereon until locked. This sleeve has a tapered adapter portion 10 which is preferably split to facilitate clamping. This split tapered portion constitutes a bearing seat and is tapered to conform to the taper of the bore of the innerring 80f the hearing. The sleeve extends .from the smaller end of the tapered seat passing along the shaft at 11 and beyond the end wall 12 of the-housing. The extreme end of this extension of the sleeve is shown turned outwardly constituting a flange 13 which is sinuous or corrugated, the waves forming opposite curved surfaces .mounting from the larger'end'when .no shaft is within indicated in the drawings by the reference,

characters 17 and 18.

Generally in practice enough clearance will be permitted by the contraction of this taortion for. permitting .the

pered seat.

the bearing-on the seat portion the'sleeve. The parts are soproportioned that when the-bearing "is mountedfion the seatzportionof thesleevehthe bearing and the entire mounting memb'er'may be freely threaded upon the shaft until the bearing has reached its-position, and then by the application'of a pairof spanners to the openings 17 and 18v and turning these in opposite directions, the cam faces cause the'seat portion l0.to. be drawn'within the bore of the bearing or relativemovement which iac- 'compli'shes. :the' same result, and with the camming movement in the proper direction 7 in relation to the relative rotation of the shaft in p t ofrthe box, .thepartsare held in locked position. I 1 r If "b Jan ment. s oul be. effected in the wrong direction and the parts come loose due to this oversight of the millwright, continued effort of the inner ring rect camming-action, and in'a very short time locking is affordeda 1 Thebearingmay be mountedupon the seat of -.th'e sleeve and the bearing and sleeve placed within the housing, the parts greased and sent to the consumer, so that the partswill notrneed to be opened'until-the time of a application arrives. And in manyapplica-t tions the boxmaybe'properly installed anding seat portion at one end tapering toward the center, the othervend of theisleeve having @a'wavedoutwardly directed flange and a collar rotatably mounted on the sleeve, and

the shaft mounted in it, and the mounting locked upon the shaft without the necessity of the millwrightin any 'way opening the box. 'Having thus described our invention, we claim and desireto secure by Letters Patent: v 1. An adapter for'use in mounting'a bearing on ashaft andcomprising'asleeve. for
